Computer issues for US Customs is leading to long lines for international passengers at some airports

The US Customs and Border Protection computer system is down at some airports including Seattle-Tacoma, creating long lines for arriving international travelers, the agency tweeted Friday afternoon.

“CBP is experiencing a temporary outage with its processing systems at various (airports) of entry & is taking immediate action to address the technology disruption,” it tweeted. “CBP officers continue to process international travelers using alternative procedures until systems are back online.

“CBP officers are working to process travelers as quickly as possible while maintaining the highest levels of security,” it said in a second tweet.

Authorities do not think there is anything nefarious about the outage, a Customs official told CNN.

John F. Kennedy International Airport in New York tweeted that passengers were being processed manually for now.
